I Built a State Management Library That Works Like React's useState
I Built a State Management Library That Works Like React's useState — Meet CreateStore If you've worked with React, you've probably used useState countless times. It's simple, predictable, and gets the job done. But as an application grows, things get a little more complicated. You have components deeply nested in the component tree that need access to the same state. Suddenly, you're passing…
I recently came across a story about a developer who created a state management library called CreateStore, which operates similarly to React's useState. In this article, I will discuss the problems faced when sharing state in React and how CreateStore aims to address these issues while keeping the API simple and intuitive for React developers.
The main challenge with sharing state in React is the need to lift state to a common parent component and pass it down through props. This approach becomes cumbersome as applications grow, especially when components are deeply nested. React Context and libraries like Redux can help, but they introduce additional complexity with providers, reducers, and action types.
CreateStore offers a solution that feels familiar to React developers without introducing unnecessary complexity. Its key features include:
1. Installing CreateStore: The package can be installed using `npm install @createstore/createstore`, with the requirement of React 19 or newer.
2. Creating a global store: By importing createStore from '@createstore/createstore', developers can create a store with custom types and initial values. For example, a store for a simple todo application could be created with two keys: todos and filter.
3. Accessing state from components: Components can access the shared state using the `useGlobalState` hook, just like they would with useState. This means that components can read and update the state without additional props or Context Providers.
4. Optional advanced features: While CreateStore starts with a simple approach, it also allows developers to enable additional features such as computed values, server data fetching, persistence, offline support, undo/redo, and cross-tab synchronization as needed.
The author of CreateStore wanted to create a library that addresses the need for global state sharing in React applications while remaining easy to use and optional. He believes this library could be useful for developers who have multiple components requiring shared state or those who want a familiar API for global state management. However, he acknowledges that simple applications may still benefit from using React's built-in useState.
In summary, CreateStore is a JavaScript state management library that simplifies sharing global state in React applications, much like React's useState does for component-specific state. It provides a straightforward API and additional optional features for more complex applications, allowing developers to add capabilities gradually as needed.
